Once sufficient crown length was present,the anterior dentition were prepared for porcelain restoration and
provisionalized.
Aesthetic rehabilitation was performed using a feldspathic
veneer system that would provide natural fluoresence
and light transmission, while neutralizing the underlying
tooth shades.

The "Hybrid Abutment": A New Design for Implant Cemented Restorations in the Esthetic ZonesCemented implant restorations are widely used by many dentists. The traditional abutment design resembles a natural tooth prepared for a crown with a similar taper and a chamfer finish line. A frequent complication associated with implant restorations in the esthetic zones is the recession of buccal gingiva over time. Abutment morphology, among several other prosthetic factors, may play an important role in the stability of gingival margin in esthetically sensitive areas, but this has never been thoroughly analyzed. With many considerations in mind and recent techniques released, this article proposes the "hybrid abutment: design (HAD), a new design that includes a combination of the two types of features - a feather edge on the buccal side, and a chamfer finish line on the lingual side. This article also presents a rationale for the use of different abutment designs for different situations.

Surface Roughness of Restroation Margin Preparations: A Comparative Analysis of Finishing TechniquesThis study compared the margin profile and surface roughness created by the tips of four different finishing instruments: fine diamond, dura white stone, tungsten carbide, and ultrasonic diamond-coated tips (UDTs). The aim was to determine which of these instruments produced the smoothest finish and created the most evenly contoured margin characteristics. It was hypothesized that UDTs would produce a rougher dentin surface than a fine diamond bur, that a tungsten carbide bur would provide a smoother finish than a fine diamond, and that the dura white stone would produce an intermediate finish.

Clinical Excellence in Operative Dentistry: Not Only A Question of Color & Fancy TrendsPredictable and repeatable results can be achieved through materials and clinical practices that, on one hand, preserve the original structure of the compromised tooth and, on the other hand, involve a very low biologic price.
This lecture aims to point out the relevant guidelines in both direct and indirect techniques for esthetic restorations through the evaluation of techniques and materials in order to reach correct, standardized and long lasting evidence based clinical results.

Choosing Anterior Ceramics – The Concept of Restorative Volume - Part 1 of 2In this lecture the author presents reviews significant literature and integrates it with clinical experience to select relevant factors that could provide a logical and practical guideline for restorative decisions in anterior teeth.The presented Concept of Restorative Volume is based on structural, optical, and periodontal factors. Each of these factors will influence the short and long-term behavior of restorations in terms of esthetics, biology, and function.

RUBBERDAMology: Tips and Tricks With IsolationIt is well known that all dental work must be under full control by operator. We always try to do our best during root canal treatment, or placing composite restorations, or luting bonded ceramic constructions. We pay a lot of attention to details and procedures, learn all new aspects of operative dentistry, follow all steps and protocols but… some time do waist our invaluable time due to challenging with moisture – saliva, bleeding, tongue, chicks, lips that are often on our way to reach the goal. And this competition is always more stressful then other most important components. Fortunately we have got great assistant for this “dirty” job that gives us stress-free conditions of working, saves our time and health and gives best ergonomics. It is rubberdam. During our lecture we will open all secrets how to use this most helpful system in operative dentistry controlling our main task – treatment.
